This is the clearest description I’ve come across of the snap-back/ terms of access provision of the proposed treaty with Iran, which (as it’s described) sounds pretty reasonable:
Iran will also immediately adhere to the Additional Protocol of the international nuclear Non-Proliferation Treaty, which allows IAEA inspectors to demand access to any site in the country, including military facilities.
Once it submits a request to Iran to visit an “undeclared” facility, the IAEA and Iran will have 14 days to agree on the terms of access. If IAEA concerns are not met within that period, a joint commission made up of the seven negotiating countries — Iran and the United States and its partners — plus the European Union, will have up to seven days to review the dispute and decide what Iran needs to do.
Only five of the eight members need to agree, effectively ensuring that Iran, Russia and China cannot prevail if they vote together. Iran then has three days to implement the decision. If it does not, “then we can begin snap-back” of sanctions, an administration official said.
